Weekly Pregnancy Guide - Week 12
 
Baby
Mother
Weight: 0.44oz 13g
Length (CRL): 1.69" 4.3cm
Heart rate : 168 bpm
Your baby's side profile has become more distinct, with its chin and nose much more prominent now.
The brain structure has completed forming and the brain mass is increasing rapidly.
Reproductive organs are developing rapidly.
Fingernails start to grow.
Amniotic fluid has been accumulating, and serves as a comfortable cushion for your baby.
By this week, you will probably have been feeling less fatigued and nauseated, though headaches and dizziness might continue or get worse with the increased blood flow.
Your uterus has been growing along with your baby and almost filling your pelvis.
From around this week, your uterus will begin to shift up and forwards, so it won't be pressing on your bladder as much.
However, as your uterus grows, the ligaments that hold up your uterus expand to accommodate it, which may cause you to feel some abdominal ache now and again.
